Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 600mm stroke and a built-in 4M210-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08A
The AirTAC SAIF40X600-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Delivering 628N of push force at 0.5MPa, it eliminates the need for a remote valve island, saving panel space and simplifying decentralized machine plumbing. The manifold connects to the cylinder via O8xO5 PU tubing, while the valve itself features a 1/4 inch port with a 16.0mm2 effective area (Cv 0.89). Driven by an AC220V terminal entry coil drawing 3.5VA, it activates in under 0.05 seconds.
Although the bare cylinder rates to 1.0MPa, the built-in valve limits the practical SAIF operating range to 0.15-0.8MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve holds its position via internal pilot pressure, not a spring. Note that neither the valve nor the adjustable air cushions provide load holding; for secure locking, consider the SAIL series.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø40mm)

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08A Is Used
Decentralized Sorting
Ideal for conveyor diverters where running individual valve tubing back to a main panel is costly. The integrated 4M210 valve switches the 600mm stroke directly from the AC220V signal.
Space-Constrained Automation
Perfect for compact assembly stations. The built-in valve manifold removes the need for a separate valve island, saving valuable machine envelope while delivering 628N push force.
Long-Stroke Transfer
Suitable for pushing parts across a 600mm distance. The self-contained pneumatic design ensures consistent speed (30-800mm/s) without complex remote plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08A the Right Choice?
Choose this 40mm bore when you need more thrust than the 32mm version (402N push at 0.5MPa) but want a smaller footprint than the 50mm option (982N push). The 600mm stroke requires careful attention to side loads—always use a guide rail to prevent rod binding and premature seal wear. The integrated 4M210 valve supports a maximum frequency of 5 cycles per second, making it suitable for fast, repetitive decentralized stations.
This AC220V terminal entry configuration suits standard industrial power grids. If your control panel lacks 220V AC, consider the DC24V (B) or AC110V (C) alternatives. When replacing, verify the 600mm stroke, 1/4 inch valve port, PT threaded cylinder port, and standard carbon steel rod. No magnet is installed, so CMSE or DMSE sensors cannot be used without modifying the configuration.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08A FAQ
At 0.5MPa, the 40mm bore provides 628N of push force and 528N of pull force. At 0.7MPa, the push force increases to 879N. The maximum push force is 128kgf at 1.0MPa, though the practical operating pressure is limited to 0.8MPa by the built-in valve.
Yes. The factory default setting retracts the piston rod when the AC220V coil is energised. By repositioning the 4M210-08 5/2 valve on the manifold block, you can reconfigure it to extend-when-energised. The valve holds its last position via internal pilot pressure, not a mechanical spring.
